Objective: To compare metabolic and cardiopulmonary responses during the 6-min walk test (6MWT) and the incremental shuttle walk test (ISWT) in patients with nCF-BCt. Methods: Twenty-one subjects (13 male; 45 ± 12 yrs; FEV1 % pred: 57 ± 7; MRC: 2 ± 1) were included. The subjects were randomized to perform two 6MWTs (30 min apart) and two ISWTs (30 min apart), on different days. The test with the best performance (greater distance) was used for comparison. During the tests, pulmonary gas exchange was measured (VO2000; Medical Graphics Corporation, St. Paul, MN). Results: See Table 1.View this table:Table 1. Variables at the peak of 6MWT and ISWT.Conclusion: Although subjects walked a greater distance in the 6MWT, both tests elicited similar physiological responses at peak exercise.
